1 Claim.

My invention relates to adjustable window shade mountings.

An important object of my invention is to provide a window shade mounting that will adjustably hold a standard type window shade, either at the top of the window sash, or at any position desired between the top of the window sash and the top of the bottom window frame.

A further object of my invention is to provide, in an adjustable window shade mounting, a rail and slide arrangement upon which the top of the said window shade may be raised or lowered as desired.

A still further object of my invention is to provide, in an adjustable window shade mounting, a pulley and ball chain arrangement together with a toothed pawl means, by which the said window shade may be maintained at any elevated position desired.

A still further object of my invention is to provide, in an adjustable window shade mounting, a leveling shaft which, together with pinions and racks, will enable the window shade mounting to be easily moved upwardly or downwardly without binding.

A still further object of my invention is to provide an adjustable window shade mounting that, by means of an adjustable leveling shaft, may be adapted to any width of window frame and window shade.

A still further object of my invention is to provide an adjustable window shade mounting that will enable the window shade to be lowered at will in order that the upper window frame may be lowered to allow air to pass in or out of the room while, at the same time, the window shade may be maintained in the lowered position required for privacy.

A still further object of my invention is to provide an adjustable window shade mounting that may be inexpensively manufactured and is easily and quickly installed in a window of any width.

Other objects and advantages inherent in my invention will become readily apparent from the ensuing description and the accompanying drawings, in which like parts are designated by like numerals, and in which:

Fig. 1 represents a front View of a window With the upper frame lowered and with my invention attached to the sash, and showing a standard type window shade mounted thereon.

Fig. 2 represents an enlarged, perspective view of my invention with portions thereof cut away, and showing the window frame and window sash in phantom lines.

2 Fig. 3 shows an enlarged, perspective view of the housing containing the pulley, ball chain, and locking pawl means of my invention with a portion of the housing cut away.

Fig. 4 shows a cross-sectional view taken substantially on line 4-4 of Fig. 1.

Fig. 5 shows a cross-sectional view taken sub-v stantiallygon line 5-5 of Fig. 4.

Generally referring to my invention by reference numeral 6; reference numerals l 'and 8 are channels having one side 3 bent over at 90. Channel I and 8 are attached by means of screws Ill, or by other suitable means, to the upper inside surfaces of window sash II, replacing sections of the moulding I2 which holds the lower window frame I4 in place. The inner side I3 of the channels 'I and 8 serve as a lguide to the said window frame I4 when it is raised. A third channel I6 is attached to the inner surfaces of the channels 'I and 8 so that its outer side 21 is in alignment twith the bent edges 9 of the channels l and 8. A bracket I'I is attached to the outside top of the channel l and supports a housing I8.

A pulley 2l is pivoted on pin 2Q within the housing I8 and supports a ball chain 22. The free end of ball chain 22 terminates in a hand grip 23; the other end 43 of the ball chain 22 is attached at 24 to the edge of a sliding bracket 25 of which there are two, one riding on each of the two channels 'I and 8. The two edges of the brackets 25 are arcuately bent at 2B to encompass slidably the outwardly bent and aligned edges 27 and 9 of the channels I6, 'I and 8. The two brackets 25 are held in horizontal alignment on the said channels IE, I and 8 by a horizontal leveling shaft 23, the ends of which are held rotatably in openings 5U in the two brackets 25. Two pinions 29 are attached to the two ends of the shaft 28 on the insides of the brackets 25. The pinions 29 ride on two racks 3|, which are mounted upon the backs of the two channels I6. The shaft 28 may consist of two or more parts which may be connected by one or more couplings 30. This is to provide adjustment means to enable my invention to be mounted on any width of window frame.

Since the shaft 28, together with the pinions 29, is rotatably mounted upon the brackets 25, which are restrained to a vertical movement by the ledges 21 and 9; therefore, the pinions 29 riding upon the racks 3| will act to keep the two brackets 25 in perfect horizontal alignment and prevent any binding during their vertical movements up or down.

A pawl 33, having teeth 34, is held pivotably by pin 32 in the lower part of the housing I8. In its locking position, as shown in Figs. 2 and 3, the toothed part 34 of the pawl 33 engages the narrow part of the ball chain 22, holding the said ball chain or a portion thereof, between the teeth 34 and the inside wall of the housing I8. The bottom of the housing I8 is open and its front part is formed outwardly into a bell-like shape I9 to provide manipulating space for the ball chain 22. A downward pull upon the chain 22, as shown in Fig. 3, will disengage the pawl 33 and drop its toothed edge 34 to the position shown in phantom lines 45.

The window shade 35 may now be adjusted` to a different level by pulling downwardlyupon, or by allowing slack in the chain 22. Then, by manipulating the chain 22 inwardly, as shown in phantom lines 44, a ball may be caused to reengage the toothed part 34 of the pawl 33 and the chain 22, together with the pawl 33, will be brought back to its former locking position, by the weight of the window shadey 35 and the mounting brackets V25, one of which attached at 24 to the chain 22. The weight or the pull of the said window shade and mounting brackets will maintain the pawl 33 and the chain 22 in a locking engagement against the inner surface ofthe housing I8.

The Window Shade 35 biiig of a standard type is supported by a, shaft 36, which has a bore on the left-hand e'Iid to hiis'eV a s'p'ig 37, the spring 31 being also attached to a rod 38 running' through the shaft 36. The rod 38 is Vsquared at its lefthand end 39 to fit into the slotted boss 440 on the outside top of the left-hand bracket 25. A boss 46 on the top of the outside of the right-Hand bracket 25 pivotably' supports the other end of the rod 38. This is a standard core Construction for supporting window shadesA and it allows the window shade 35 to be adjusted to any desired length by means of the attached cor'd 4I. Thus. if it is desired to lower' the top window' frame I5 to allow air, as shown by arrows 42, to pass in or out of the window but, at the same time, keep the window shade in a lowered position to maintain privacy, a single pull on the chain '2`2 will adjust the' top of the window shade 35' to a p'os'ition even with the top of the lowered window frame I5, providing ventilation and desired privacy at the same time. This combination is not 4 possible with window shade mountings in common use.

While I have described a preferred form of my invention, yet I desire it to be understood that the structure described may be modied in formal details, such as by the substitution of mechanical equivalents employed; my invention to be limited only by the subjoined claim which states the invention in terms commensurate with the broad and specific aspects thereof.

Having thus described and revealed my invention, whatI claim as new and desire to secure by Letters Patent is:

Beaded chain and pawl locking means, comprising a housing having an outwardly formed bell-like end portion, grooved pulley means rotatably `mounted within the said housing with its groove in the plane of the said bell-like end portion, beaded chain means trained over the said grooved pulley means, toothed pawl means pivotally mounted Within the said housing in trans# verse relationship to the plane of the said beaded chain means and to the said bell-like end portion, the said toothed pawl means having its toothed portion of greater length than the distance between its point of mounting and the inner wall of theV said bell-like end portion in order to permit the said toothed portion toV engage the said beaded chain means when one end of the said beaded chain means is pulled, and to effect release of the said toothed portion from engagement with the said beaded chain means when the other end of the said beaded chain means is pulled.
